Karthick Sankarachary commented on ODE-508:
-------------------------------------------
As you can tell by the link, this issue is essentially a duplicate of ODE-498,
which was recently fixed in the 1.X branch. Sure enough, when I forward ported
that fix to the trunk (see revision 741748), it resolved this issue as well.
Additionally, the test case attached herein has been incorporated into the BPEL
test case as well. For more details on that, please take a look at the change
below, which should serve as a good starting point:
